Environment Protection Authority v Clarence Colliery Pty Ltd; Chief Executive, Office of Environment and Heritage v Clarence Colliery Pty Ltd

The Environmental Protection Authority (EPA) and Chief Executive, Office of Environment and Heritage (CEO) brought proceedings against Clarence Colliery Pty Ltd for breaches of the Protection of the Environment Operations Act 1997 (POEO Act) and the Coal Mining Management Act 2013 (CMMA). The EPA and CEO sought penalties and declarations against the company for environmental non-compliance related to coal mining operations. The dispute was heard in the Land and Environment Court of New South Wales, presided over by Justice Cumner.

The court had to determine whether Clarence Colliery Pty Ltd had indeed breached provisions of the POEO Act and the CMMA by failing to comply with certain environmental conditions attached to its mining licence. Specifically, the court had to assess whether the company's actions, or inactions, had caused environmental harm or had the potential to cause significant harm to the environment. The validity of the penalties imposed and the appropriateness of the declarations sought by the EPA and CEO were also scrutinized.

Justice Cumner found that Clarence Colliery Pty Ltd had contravened the conditions of its mining licence by failing to implement adequate measures to prevent water pollution and by not adequately controlling dust and noise. The court held that these breaches had caused environmental harm and had the potential for significant harm. The judge accepted the arguments presented by the EPA and CEO and found the penalties imposed to be appropriate given the seriousness of the breaches. Consequently, Justice Cumner ordered the company to pay the penalties and issued the declarations sought by the EPA and CEO.
